Application filed April 17, 1922. Serial No. 553,858.

To (1U 'zr/iom it may concern Be it known that I, I'IILRAH A.Cons'rocir, a citizen of the United States, residing at Thomaston, inthe county of Knox and State of Maine, have invented a new and usefulKnife, of which the following is a specification.

This invention relates to cutlery and aims to provide novel means forprotecting the cutting edge of the blade of a. knife against contactwith material to dull the. cutting edge, when the knife is not in use.

Another object of the invention is to provide a knife wherein the blademay be moved to a position within the handle, novel means being providedfor locking the blade in such position. I

A still further object of the invention is to provide a guard or supportfor the knife to hold the blade thereof out of contact with the surfaceon which the knife is positioned, the guard being of a structure toautomatically move to its active position with the moving of the bladeto its open position.

lVit-h the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing Figure 1 is a. side elevational View of avknife constructed in accordance with the present invention anddisclosing the blade moving to its active posit-ion.

Figure 2 is a view disclosing the back of the knife when the blade is inits active position.

Figure 3 is a. fragmental elevational view disclosing the connectionbetween the handleand blade, one section of the handle being removed.

Figure l is a sectional view taken on line l-% of Figure 1.

Figure 5 is a. sectional view taken on line 5-5 of Figure 1.

Referring to the drawing in detail, the reference character 5 designatesthe handle portion of the knife, which may be of any suitableconstruction, but in the present showing is in the form of a length ofsheet inetahbent intermediate its ends to provide the sides of thehandle, which sides are held in spaced relation as by means of atransversely extending pin (5. The blade is indi cated at 7 and may beof any desired construction, the same being shown as pivotally supportedbetween the side members of the handle 5, as by means of the pivot pin8.

Formed on the inner end of the blade 7 is an ear 9 adapted to contactwith the wall 10 of the guard ll, which is shown as pivotally supportedbetween. the side members of the handle as at. 12. in car 13 is formedon the blade 7 adjacent to the lower edge thereof, which car is adaptedto contact with the extension ll of the guard 11 when the blade ismoving to its closed position to the end that the guard is returned toits inactive position, automatically; The engagement of the ear 9 withthe shoulder 10, auto matically moves the guard 11 to its activeposition, when the blade is moved from a position within the handleportion.

The locking structure embodies an arm indicated at 15 secured to thehandle as at 16, the arm being formed with curved portions 17 and 18respectively, which curved portions lie in spaced relation with thehandle, to cause the outerend of the arm to move away from the handleportion when the thumb of the user of the knife is pressed on the curvedportion 17. T he outer end of the arm 15 is bifurcated to fit under thehead 19 of the pin 20, whereby movement of the arm as described, willresult in the pin 19 being moved within its opening, itbeing understoodthat openings are formed in the handle, which openings may register withopenings 20 and 21 of the blade, for holding the blade in either itsopen or closed position.

Having thus described the invention, what is claimed as new is 1. knifecomprising a handle portion, a blade pivotally connected to the handleportion, and having openings disposed on opposite sides of its pivot, amovable pin carried by the handle portion and adapted to extend throughthe handle portion and engage in the opening of the blade disposedadjacent thereto, and a guard pivotally supported by the handle andadapted to be moved to its activefposition simultaneously with themovement of the blade to its active position.

2. A knife comprising a handle portion, a, blade pivotally supported bythe h endle portion and having spaced ears. a. guard pivotally supportedby the handle, an extension forminge part of the guard and adapted tocontact with one of the ears to move the guard to its active positionwhen the blade is moved to its active position.
